Answer:
Here's what I get.
Step-by-step explanation:
1. Convert the mixed number to an improper fraction
2. Invert the proper fraction and change division to multiplication
3. Multiply numerators and denominators
4. Divide the numerator and the denominator
The quotient is what you get after you invert the denominator in Step 2 and then multiply the two fractions in Step 3.
Answer: To find the equation of the circle, it is not necessary to find the legs of the triangle first.
The length of the legs (equal) is 3√2 or 4.243
Step-by-step explanation:
The equation for a circle is similar to the Pythagorean Theorem
a² + b² = c²
( x - h )² + ( y - k )² = r², where ( h, k ) is the center and r is the radius.
The a and b terms are changed to allow insertion of h and k to locate the center of the circle on a Cartesian plane.
You can get the information needed from
Given: radius =6 and "a center at the point (3,2)"
Substitute 3 for h and 2 for k and 6 for r
( x - 3 )² + ( y - 2 )² = 6² This is the equation of the circle .
From the diagram, it appears that x-3 = y-2
So, in the equation, we can substitute 2(x²) = 36
x² = 36/2 . x² = 18
√x² = √18 = √9(2)
x = 3√2 =4.2426
the length of the horizontal leg is 4.243
Substitute for x in to find x+3 the coordinate (x,2)
the coordinate x, 2 is (7.24, 2)
Substitute for y in to find y+2, the length of the vertical leg is 4.243.
y + 2 = 6.243
So the coordinate (x,y) on the circle is (7.24, 6.24)
This does not account for Step 1 and Step 2 in the question, matching expressions or equations to the steps. I hope you will be able to sort that our with the information here.
